Shop Ra-flect Radiant Barrier

Start with the assembly, then choose the roll width that matches your framing. Square footage determines how many rolls you need; width determines how easy the installation will be.

Recommended if unsure

Laser Perforated (LP)

The safer choice for most vented attics and breathable assemblies. Tiny perforations let moisture vapor pass while the reflective surfaces reduce radiant heat transfer.

Non-perforated

Vapor Barrier (VB)

Choose Vapor Barrier (VB) only when the assembly intentionally needs vapor control, such as selected floors, crawl spaces, or radon-barrier applications.
